Entropy production and lost work for irreversible processes [PDF]

open access: yes, 2006
In this paper we analyse in depth the Lost Work in an irreversible process (i.e. IRREV REV Lost ) W =W -W . This quantity is also called ‘degraded energy’ or ‘Energy unavailable to do work’. Usually in textbooks one can find the relation Lost U W o TDS .

The Maximum Entropy Production Principle: Its Theoretical Foundations and Applications to the Earth System [PDF]

open access: yes, 2010
The Maximum Entropy Production (MEP) principle has been remarkably successful in producing accurate predictions for non-equilibrium states. We argue that this is because the MEP principle is an effective inference procedure that produces the best ...

Entropy Production in Quantum is Different [PDF]

open access: yesEntropy, 2019
Currently, ‘time’ does not play any essential role in quantum information theory. In this sense, quantum information theory is underdeveloped similarly to how quantum physics was underdeveloped before Erwin Schrödinger introduced his famous equation for the evolution of a quantum wave function.

Entropy Production in Thermostats II [PDF]

open access: yesJournal of Statistical Physics, 2007
We show that an arbitrary Anosov Gaussian thermostat close to equilibrium has positive entropy poduction unless the external field $E$ has a global potential. The configuration space is allowed to have any dimension and magnetic forces are also allowed. We also show the following non-perturbative result.

A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems

open access: yesEntropy, 2022
Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

The Role of Vegetation on the Ecosystem Radiative Entropy Budget and Trends Along Ecological Succession

open access: yesEntropy, 2014
Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.

Entropy and entropy production in some applications [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2014
By using entropy and entropy production, we calculate the steady flux of some phenomena. The method we use is a competition method, $S_S/τ+σ={\it maximum}$, where $S_S$ is system entropy, $σ$ is entropy production and $τ$ is microscopic interaction time. System entropy is calculated from the equilibrium state by studying the flux fluctuations.

Quantifying the thermodynamic entropy budget of the land surface: is this useful? [PDF]

open access: yesEarth System Dynamics, 2011
As a system is moved away from a state of thermodynamic equilibrium, spatial and temporal heterogeneity is induced. A possible methodology to assess these impacts is to examine the thermodynamic entropy budget and assess the role of entropy production ...

Entropy Production Rates of the Climate [PDF]

open access: yesJournal of the Atmospheric Sciences, 2020
AbstractThere is ongoing interest in the global entropy production rate as a climate diagnostic and predictor, but progress has been limited by ambiguities in its definition; different conceptual boundaries of the climate system give rise to different internal production rates.
